British helmet with net

A few pics of one of my helmets, not sure origin of the net but came with the lid so I left as is, also the helmet seems to have had a white over wash at some point in its life , as in the scratches and where the rim joins the shell the remains of this wash is visible. Does any one know if the net is American as I sure it's not a Brit one.
